1)What is the Molarity of a solution that contains 3.78g ofH2C2O4.2H2O in 200 mL of a solution?
2) If 50.0 mL of NaOH solution is required to react completely with 0.62g KHP, What is the molarity of the NaOH?
3) In the titration of an impure sample of KHP, it was found that 30.6 mL of 0.100 M NaOH was required to react completely with 0.745 g of sample. What is the percentage of the KHP in this sample?
